The article deals with the development and study of electromechanical adaptive lateral motion control systems for aircraft of light and ultralight classes, which are increasingly used due to the demand for their tactical and technical characteristics. Nonlinear and linearized mathematical models of the dynamics of the lateral movement of the aircraft are constructed, taking into account and not taking into account the electromagnetic dynamics of the executive electric drive of the steering organ. Assuming that in both cases of mathematical models as control objects, the matching conditions are violated, the parameters of the linear parts are unknown, and the nonlinear part is a limited function, the sequential compensator method is considered for constructing adaptive systems. The results of computer studies of the effectiveness of the constructed electromechanical adaptive systems in achieving dynamic stability and performance under the influence of electromagnetic dynamics, treated either as a singular perturbation or taking into account its mathematical model, are presented. Computer simulation has also demonstrated the effectiveness of the sequential compensator method in ensuring the stability of lateral movement to the action of wind disturbances. The studies were carried out on the basis of the calculation model of the UAV-70V light unmanned aerial vehicle (weighing 65 kg) of the Aerospase Academy company (Vietnam), designed for remote monitoring of underlying surfaces.
